I have tried to run the program but I don't seem to getting anything from it and I have made sure 3-4 times that the code had been entered correctly, which it was.

I know I have to enter the coefficients before I run the program (XEQ S) but where do I enter them at? I tried XEQ I and XEQ J, but nothing. Can someone please walk me through this program; not the code, just using the program? I would greatly appreciate someone giving me an exact run through with a 3X3 example.

Thanks Ben!! The program in the hp 33s manual has it to where you press the XEQ A key and then you are prompted for each coefficient, but this program is different.

I now am able to use this program. I was trying to find the keys that would prompt me, but now I know I must enter the number then STO the number to the letter. Still more learning about this calc. to go.
